Midrasch zu Wajikra 5:19

3) "And he shall bring": Even after Yom Kippur. (For Yom Kippur atones only for transgressions that are not known [to the sinner] upon it) "his guilt-offering": "his guilt-offering" is written here and elsewhere (Vayikra 5:19): ("It is a guilt-offering; a guilt-offering, a guilt-offering to the L–rd.") Just as with his guilt-offering there, its surplus monies are used for a donative offering, so, with his guilt-offering here, its surplus monies are used for a donative offering.

3) (Vayikra 5:19): "It is a guilt-offering; he has been guilty (ashom asham) to the L–rd." Whence is it derived that if one brought a suspended guilt-offering, slaughtered it and sprinkled its blood, and afterwards it became known to him that he had sinned or it became known to him that he had not sinned — whence is it derived that he may eat it (and it is not reckoned as non-consecrated food (chullin) slaughtered in the Temple court)? From "a guilt-offering." I might think (this to be so) even if the blood has not been sprinkled. It is, therefore, written "It." What is to be done with it? The blood is spilled out and the flesh goes to the "house of burning." If the blood has been sprinkled it may be eaten. R. Yossi says: Even if the blood is in the vessel, it may be sprinkled and the flesh eaten.

4) I might think that even if it has not been slaughtered, (it should be slaughtered); it is, therefore, written "It" (to exclude such an instance.) What is to be done with it? It is to go out to pasture with the flock, (it being regarded as any other animal). These are the words of R. Meir. The sages say: It is to graze until it contracts some blemish, after which it is sold and its monies used for a (communal) guilt-offering. R. Elazar says: It is to be offered up; for if it does not come for this sin, it comes for some other sin.
